Functions ¶
func InternString ¶
InternString returns interned s.
This may be needed for reducing the amounts of allocated memory.
func Itoa ¶
Itoa returns string representation of n.
This function doesn't allocate memory on repeated calls for the same n.
func ResizeNoCopyMayOverallocate ¶
ResizeNoCopyMayOverallocate resizes b to minimum n bytes and returns the resized buffer (which may be newly allocated).
If newly allocated buffer is returned then b contents isn't copied to it.
func ResizeNoCopyNoOverallocate ¶
ResizeNoCopyNoOverallocate resizes b to exactly n bytes and returns the resized buffer (which may be newly allocated).
If newly allocated buffer is returned then b contents isn't copied to it.
func ResizeWithCopyMayOverallocate ¶
ResizeWithCopyMayOverallocate resizes b to minimum n bytes and returns the resized buffer (which may be newly allocated).
If newly allocated buffer is returned then b contents is copied to it.
func ResizeWithCopyNoOverallocate ¶
ResizeWithCopyNoOverallocate resizes b to exactly n bytes and returns the resized buffer (which may be newly allocated).
If newly allocated buffer is returned then b contents is copied to it.
func ToUnsafeBytes ¶
ToUnsafeBytes converts s to a byte slice without memory allocations.
The returned byte slice is valid only until s is reachable and unmodified.
func ToUnsafeString ¶
ToUnsafeString converts b to string without memory allocations.
The returned string is valid only until b is reachable and unmodified.
Types ¶
type ByteBuffer ¶
type ByteBuffer struct {
// B is the underlying byte slice.
B []byte
}
ByteBuffer implements a simple byte buffer.
func (*ByteBuffer) MustClose ¶
func (bb *ByteBuffer) MustClose()
MustClose closes bb for subsequent re-use.
func (*ByteBuffer) MustReadAt ¶
func (bb *ByteBuffer) MustReadAt(p []byte, offset int64)
MustReadAt reads len(p) bytes starting from the given offset.
type ByteBufferPool ¶
type ByteBufferPool struct {
// contains filtered or unexported fields
}
ByteBufferPool is a pool of ByteBuffers.
func (*ByteBufferPool) Get ¶
func (bbp *ByteBufferPool) Get() *ByteBuffer
Get obtains a ByteBuffer from bbp.
type FastStringMatcher ¶
type FastStringMatcher struct {
// contains filtered or unexported fields
}
FastStringMatcher implements fast matcher for strings.
It caches string match results and returns them back on the next calls without calling the matchFunc, which may be expensive.
func NewFastStringMatcher ¶
func NewFastStringMatcher(matchFunc func(s string) bool) *FastStringMatcher
NewFastStringMatcher creates new matcher, which applies matchFunc to strings passed to Match()
matchFunc must return the same result for the same input.
func (*FastStringMatcher) Match ¶
func (fsm *FastStringMatcher) Match(s string) bool
Match applies matchFunc to s and returns the result.
type FastStringTransformer ¶
type FastStringTransformer struct {
// contains filtered or unexported fields
}
FastStringTransformer implements fast transformer for strings.
It caches transformed strings and returns them back on the next calls without calling the transformFunc, which may be expensive.
func NewFastStringTransformer ¶
func NewFastStringTransformer(transformFunc func(s string) string) *FastStringTransformer
NewFastStringTransformer creates new transformer, which applies transformFunc to strings passed to Transform()
transformFunc must return the same result for the same input.
func (*FastStringTransformer) Transform ¶
func (fst *FastStringTransformer) Transform(s string) string
Transform applies transformFunc to s and returns the result.
